Principal Analog Design Engineer

ABOUT NEUROPHOS The demand for new data centers and AI compute is rapidly outpacing the planet's energy capacity. Digital solutions are hitting a power wall as we approach the physical limits of traditional silicon. Conquering this bottleneck means rethinking the fundamental architecture of inference compute. The industry's current path can't meet the need, so we're taking a different approach. Instead of traditional electronic circuits, we use silicon photonics and an active, programmable metasurface to perform matrix multiplications at the speed of light. Our optical cells are 10,000x smaller than traditional photonic components, enabling unprecedented density. By using photonics instead of electricity, our chips become more efficient as they scale. This architecture will deliver up to 100 times the energy efficiency of existing solutions while significantly improving performance for large-scale AI inference. We’ve assembled a world-class team of industry veterans and recently raised a $110M Series A https://www.neurophos.com/110m-raise led by Gates Frontier. Participants include M12 (Microsoft’s Venture Fund), Carbon Direct Capital, Aramco Ventures, Bosch Ventures, Tectonic Ventures, Space Capital, and others. Join us and shape the future of computing! Position Overview: We are seeking a seasoned Principal Analog Design Engineer to play a vital role in developing cutting-edge full-custom electronic transceiver components that interface directly with our custom silicon photonics and are essential to our revolutionary photonic AI platform. You will own the full lifecycle of analog blocks, from specification and architecture to tape-out-ready layout. Success in this role requires a deep understanding of transistor-level circuit design, linearity, noise performance, and signal integrity in CMOS processes up to GHz speeds. If you possess a proven track record of designing robust, ultra-fast analog circuits and are eager to work at the intersection of electronics and photonics, you will make a defining impact on the future of optical computing.
